Filed: 1992-11-09
Abstract: PURPOSE:To simplify an adjusting operation of an optical axis by cutting a mounting surface of an ultrasonic transducer of a quartz glass comprising an AOQ so that an angle to the transmission surfaces of a laser beam is a Bragg angle. CONSTITUTION:In an AOQ 30, a mounting surface of an ultrasonic transducer 32 of a quartz glass 34 is previously out so that the mounting surface is a Bragg angle QB to the laser transmission surfaces 36 and 38. For example, when a wavelength 1064nm of a laser of Nd: YAG is Q-switched by a transverse ultrasonic wave, the cutting may be performed so that the Bragg angle QB is 4.2 deg.. In this case, a reflection preventive film is formed on the transmission surfaces 36 and 38 of the laser beam. When the AOQ 30 having such a construction is used in a laser resonator, after adjusting an optical axis, an adjustment to the Bragg angle of the AOQ 30 is performed by only the installation so that the transmission surfaces 36 and 38 of the laser beam of the AOQ 30 are parallel to a partial reflecting mirror 14. Thus, the adjusting operation of the optical axis is simplified.
